BOTTLE STOPPEB Application filed January 12, 1929, Serial No. 332,081. Renewed June 9, 1932.

m At the present time a stopper of this nature is particularly adapted for use for bottles containing cologne, toilet water, hair tome and various other similar liquids.

in carrying out the invention the stopper made in accordance therewith is preferably so constructed as to include a body member having a shank adapted to fit the neck of the bottle. The shank is provided with a cup suitably connected thereto and forming closure or casing for a valve device which permits the passage of a liquid from the bottle and prevents the passage of a liquid to the bottle. This stopper structure may be placed and secured in the neck of the bottle in any desired manner and will be hereinafter more particularly described.

In the drawing Fig. 1 is a central longitudinal section of a bottle stopper made in accordance with my present invention,

Fig. 2 is a sectional plan on line 22, Fig. 1,

Fig. 3 is a sectional plan on l1ne 33, Fig. 1, and

Fig. 4 is a sectional plan on llne 4l4, Fig. l.

Referring to the drawing a portion of a neck of a bottle is indicated at 10. In carrying out the invention I employ a sleeve which is indicated at 11 and is preferably cylindrical, made of cork or other like material and with an outer diameter substantially that of the inner diameter of the neck of the bottle. The stopper member also includes a plug made of porcelain or like material and formed to include a head or crown 12 and a shank 13. The crown or head 12 in suitable positions is provided with flat faces, as indicated at 14 and in the shank member of the plug there is a series of longitudinal passages 16, 17 and 18 extending from the inner end of the shank to the head or crown and terminating immediately beneath the latter, it being understood that there is a longitudinal passage in the plug for each of the flattened peripheral portions on the head or crown. In the upper surface of the head or crown I may employ a series of recesses 19 by means of which and a suitable tool the parts of the stopper may be readily inserted in the neck of the bottle. In the shank member 13 there is a circumferential recess indicated at 20, the purpose of which will be hereinafter described. As will be understood and as is illustrated the depth of this circumferential recess is appreciably less than the depth of the said vertical passages.

Inter-posed between the sleeve 11 and the plug memberI employ a cup member 21.

This cup member 21 is preferably made of sheet metal and at its upper or outer end is provided with a flange 22 adapted to lie upon the upper surface of the sleeve 11 which may function as a support therefor while the flange also fits into a shoulder 23 provided therefor in the shank of the plug. At its lower or inner end the cup member 21 is provided with a port or passage 24 and this cup member is preferably secured in position relatively to the shank by a series of indentations 25 preferably three in number although, as will-be understood, any necessary number may be employed. These indentations 25 provide bosses on the inner surface of the cup which extend into the circumferential recess 20 and by means of which, as hereinbefore stated, the cup mem her is secured in position. Inasmuch, however, as the depth of the vertical passages is materially greater than the depth of the circumferential recess these bosses do not interfere with the passage of the liquid from the bottle even if they are made to be coincident with the said vertical passages. Also lying within the cup member I may employ a washer 26 provided with an opening or port 27 therein with the same diameter and adapted to register with the port 24 in the bottom of the cup.

Th lower or inner end of the cup is inner end of the shank.

spaced appreciably from the inner end of the shank member of the plug so as to provide a chamber 28 within the cup and between the inner end of the same and the In this chan'iber I employ a valve 29 which may be made of porcelain, or fibre, or other similar material adapted to serve the purpose of the valve.

When a bottle fitted with the stopper as hereinbcfore described is inverted. for the purpose of emptying the contents thereof the valve 29 uncovers the port in the bottom of the cup and permits the liquid to pass through this port to and through the passages in the shank and thence to pass by the flattened portions of the periphery of the head. or crown of the plug and out of the neck of the bottle. Also when the bottle has been emptied the valve 29 acts as a check to prevent the passage of a liquid into the bottle and consequently the bottle cannot be satisfactorily refilled When the stopper is in place in the neck thereof.

1 claim as my invention:

1. In a device of the class described, the combination of a bottle neck, a resilient sleeve inserted in said bottle neck, a cup supported by said sleeve, a plug in said cup, means for holding the plug in place, said means consisting of a set of three indentations formed in the wall of the cup and adapted to eo-act with a slot formed in the neck of the plug for locking the said cup and plug together, a valve resting in the bottom of the said cup above an opening therein, a series of vertical slots in the neck of said plug and a series of flattened portions in the crown of said plug, said valve when the bottle is tilted adapted to admit liquid through said hole in the bottom of the cup and thence to the vertical slots and said flattened portions, and thence to the neck opening of the bottle, said valve when the bottle is in its upright position adapted to prevent any liquid from entering the bottle.

2. In a device of the class described, the combination of a bottle neck, a resilient sleeve inserted in said bottle neck, a flanged cup supported Within said sleeve, a plug in said cup, means for holding said plug in place, said means consisting of a set of three indentations formed in thewall of the cup and adapted to coact with a slot formed in the neck of the plug and adapted to lock the cup and plug together, a valve resting in the bottom of said cup above an opening therein, a series oi vertical slots formed in the neck of said plug, the depth ot' said vertical slots being greater than the depth of the first mentioned slot, and a series of flattened portions in the crown of said plug, said valve when the bottle is tilted adapted to admit liquid through said hole in the bottom of the cup and thence to the vertical slots and said flattened portions, and thence to the neck opening of the bottle, said Valve when the bottle is in its uprightposition adapted to prevent any liquid from entering the bottle.
